To all wh'o'm it may concern:

Be it known that I, FREDERIC W. HIL- LARD, a resident of Tottenville, in the county of Richmond and cityand State of New York, have invented certain new and useful Improvements in Type-VVritin Machines,

of which the'followingis a speci cation.

' My invention is an improvement in- .typewrltlng mach nes, lts'primary aim belng to produce atype'writer with the double ad vantage of ri'ntin'g in sight and with a whole typerln'g in which to'pivot the type bars,

I T ewriters heretofore constructed are div1s1b e into two'classes, v1z., those in whlch theprinting'is doneou't of sight but which I are provided with whole type rings for the typebars, an'd thosewhich print in sight butwhich'ar'e only provided with arcs of type rings'for the type bars; My invention cornbines'the a'dvantages'of' each of the two classes without their disadvantages. As illustrating' 'my meaning, the circle in which the typefbarsare' pivoted, may be considered as comprising the four quadrants, or 90 detype barsare' pivotedin' all our such arcs,

heretofor'e in use, thejwhole set of -t e bars is comprised wlthintwo, andusua ly less soniptionfifinia be saidthat my set of type bars comprise our seriesof bars, viz. those pivoted in the quadrant at the top of the ircle, those ivoted in the two quadrants the'one att "e right and the other at the left hand side of the circle, and those pivoted in thequadrantat the bottom of the circle;

thewho-le' set thusbingcOmpried in four arcs of 90 de rees each, It is convenient to thus class tlie bars, as those in each arc 'flie norma" in different relation to the remainder of't "e machinefrom those of all the other arcs, strike in diflerentdirections to the pl'aten and bear diflerent relations to theirkey levers;

M invention also comprises the detail mec anism for embod ing my invention. Much of this detail w 'ich is novel is applicable to typewriters heretofore in use. I

drawings 1st my improved typewrltmg machine I withjfthe mechanism illustrated in detail, and, 2nd,many novelfeatures of 'mechanismywhich are applicable to other type ing in the visua line between the o erator and. the printing point and the near y portion of the platen. 1

2nd. A aper-carriage which is shifta-ble to a plurality of printing positions at different levels, in combination with means for lifting the platen into View above any printing position and relatively to a typebar support, as for inspection and correction of the type-written work, and in combination with a series of type-bars on said support.

3rd. A movable or vibratory 1nking ribbon between the type-bar support and the platen, arranged and adapted, in combination with the described printing mechanism, to be brought over the" printing point at the moment of impact of 'a character and to then be retracted awayfrom the platen and out of the visual line between the operator and the printin'gll. oint.

4th. he combination with a series of ty e-bars, of two series of'con'necting wires or links extending in different directions, the one series of links extending-in a direction substantially parallel with the normal positions of then type-bars and the other series extendin upwardly from the key-levers, and bell-cranr levers between the two series of links, having prolonged axes extending trans versely of the machme, each bell-crank having an arm practically in line with its typebar and connected thereto by one of the ty ebar links, and also having an arm practica lly in line with its 'key-lever and connected therewith by a key-lever link; so as to connect va type-bar in one'position transverse the machine with a key-lever in another position transverse the machine.

5th. Type-bars mounted on the type-bar support above the line of vision, connected to rock-shafts or bell-cranks having prolonged] axes extending transversely of the machine, in combination with connectin wires or links which are substantially ara lelwith the type-bars and attached t ereto and to the inner ends of the rock-shafts above the line of vision, and other connecting-wires or links which are attached to keylevers to one side of the visual line and to the outer ends of the rock-shafts; so that the type-bars pivoted above the line of vision may be connected .to key-levers onone side or other of the machine, thus leaving the visual line between the operator and the laten wholly unobstructed by the key-lever point; the said upper series of type-bars and their links lying in the central transverse section of the machine, with the corresponding series of key-levers and their links spread apart right and left and occupying a wider transverse section of the machine.

6th. Two key-levers connected to the same type-bar by slotted connections, one of the key-levers being connected with the single so side elevation in the same position as Fig. 1.

but with all the parts in place, exceptingthat some details are omitted. Fig. 3. 1s a plan view of the machine. Fig. 4. is a front view, showing the machine as it appears to the operator. In this view the mechanism for feeding the inking ribbon is omitted. Fig. 5.; is a detail view of the laten shifting mechanism showing the positions of the parts in theirnormal state in full lines, and -10 the positions of most of the 1parts in their two shifted stats in dotted ines. Fig. 6. is a detail view of a rock shaft which connects the same type bar with three levers, and of the connecting wire between the rock shaft and thetype bar, and the two slotted connecting wires which extend to two key levers, and the wire which formsthe connection between the type bar and the carriage propelling power. ig. 7. is a longitudinal section of a side elevation of some of the parts shown in Fig. 1, showing the type bar, rock shaft and connecting wlres illustrated in Fig. 9, as they appear in the machine. Figs. 8, 9 and 10 are enlarged detail views of the type-bar and vibratory platen shown in Figs. 5 and 7. Fig. 8 is a view of the platen and type-bar in the central printing position, shown in Fig. 7, with the ty e bar at the printing point, corresponding t the full line position of Fig. 5. 9 shows the platen shifted to the lower printing position, corresponding to the lower position thereof shown in dotted lines in Fig. 5, and the type bar at the printing point. And 10 is a similar view with the platen in its upper inks at and inithe vicinity of the printing printin position, corres onding to the upper dotted line position of ig. 5, with the typebar at the printing point.

Fig. 1 shows a sectional view of the base frame, 1. Extending in a perpendicular direction from the back portion of the base frame are the brackets 2 for the carriage guide rail 3 and the parts mounted on the guids rail. The principal parts which are mounted on the guide rail are the paper carriage 4, the rack 5, and the carriage shifting frame 6. At the front of the machine is placed the key board. Intermediate between the paper carriage and the key board the type bar plate 7 is mounted on the base frame of the machine. The type bar plate inclines backward at a slight angle from the perpendicular plane. Fig. 1 shows a sectional view of the type bar plate, taken on the line Y Y of Fig. 3. The type bar plate comprises a ring with type bars mounted concentrically thereon and pivoted in the ,usual manner so that they can all strike through the ,central opening in the ring to a common rinting center on the platen 8. The type Ear plate is inclined slightly backward from the perpendicular in order that the line of vision between the operatoron the machine and the printing center may be clear and unobstructed. There is a central opening through the casing ,9 which guards t e type bar plate. Through this central 0 ening the writing on the platen may be 0 early seen by the operatoras soon as each letter has been rinted. This is clearly shown in Fig. 4, w ch shows the printing as it appearsto the operator. By this arrangement Lam enabled to secure a whole type ring in which to pivot the type bars, and I- also secure the additional advantage of printing in sight. Heretofore type writing machines have either been constructed to print out of sight or else the ty e bars have all been mounted in only one ha f of the type ring. By my present construction I have secured the advantages of both'classes of machines without their disadvantages.

B an inspection of Fig. 4 of the drawings it will be seen that, although there are typebars mounted entirely around the t 'pe-ring, and some of them directly above t e visual between the operator and the platen, there are no key-lever connecting-wires in view of the operator as he looks through the open s ace. in the casing 9- toward the platen.

his is due to'the use of the two series of connecting-wires 18 and 22 and the bellcrank levers 21 having prolonged axes extending transversely of the machine, by means of which the upper central series of typp-bars is connected to key-levers at the rig t hand and left hand sides of'the machine, whose upwardly extending connecting-wires 22 lie within the casing and wholly to one side or the other of the opening 130 features.

therein through which the operator views his work.

In order to fully carry out my design of machine I use the, following additional The inking ribbon is mounted on the s ools 11 and is fed from one spool to the ot er by'the ratchets 12 and the pawls wirewith the rocker frame 14..

13, which are connected with the dog carrying rocker frame 14. The ribbon is fed when the" rocker frame is operated. The ribbon at its lower end is connected by a connecting When a type key is depressed the rocker frame is rocked and the -r1bbon guide with the ribbon vibrated to the printing center; and when the key is released the ribbon guide and ribbon are vibrated away from the platen again out of the line of vision of the operator, as is clearly shown by the arrow in Fig. 1 and as is shown in Fig. 4. In Fig. 4 the ribbon is shown in normal place below the line of writing.

manner by sim le connecting wires.

method by whic Iconnect them isasfol- The type bars are connected with the key levers 17 and are operated when the key levers are depressed. Owing to their positions in the type ring they cannot be connected to the key levers in the ordinary The lows: I attach a connecting wire 18 to each These conbars when at rest. At their front ends the are attached tov the inner'ends of the be I crank levers 19. To the outer ends of the 7 bell crank levers are attached a second set of connecting wires 20 or 22; and these latter wires are extended downwardly and connectedwith the key levers, in the usual manner. As above stated I have also pro- .vide'd'means for keeping the s ace in front of the printing center on thep aten clear of connecting wires so as not to obstruct the view of the writing. In order to accomplish this I have substituted rock shafts 21, (see Fig. tilinplace of the bell crank levers. By attaching the connecting wire 18 to the end of the rock shaft directly above the line of vision and the connecting wire 20' to the other. end of the rock shaft I remove the connecting wire 20 out of line of vision between the operator and the platen.

this purpose the other connecting wire 20 rear edge on the guide rail 3 and is fastened For and the-wire 22 should be omitted.

I From an inspection of Fig. 1 of the drawings it will beseen that the type-bar connectbar in the upper half of the type-bar ring (and having its inner rocker-arm 1n line with its connected type-bar) must have its axis prolonged to a point outside of or beyond the extreme right hand or left hand type-bars at the sides of the ring, so that the connecting wire 20 or 22 which extends upwardly from one of the key levers at the side of the machine ma connect with the outer rockerarm of the rock-shaft without. interfering with the type-bars at the sides of the typebar ring. Hence also thekey-lever system must be wider than the type-bar system, as it is clearly seen to be in Fig. 4 of the drawings. The casing 9 is, however, made wider than the key-lever system so as to in'close and protect all of the connecting-wires 18, 20

and 22 and the several rock-shafts 21, as well as the'system of type-bars and key-levers:

The arrangement of the type keys in the key board is that of the Remin ton Standard typewriter, excepting that in the next to the top row of keys I have laced a row of double spacing keys whic are connected with the type characters which are frequently terminal characters. The row of double spacing keys is distinguished from the. remainder of the keys by being black with white letters, while the other keys are white with black letters.

In my present construction I show an improved form of connecting two keys with the same type bar, and one of the keys with the sin le spacing mechanism and the other key wit the double spacing mechanism. This improvement consists in a third wire which is connected to the same type barand to the spacing mechanism. Its object is to bring e force of the carriage main spring to bear on the type bar to start it back to normal position after the printing has taken lace, as will be hereinafter fully described. he construction of this device is shown in Figs. 6 and 7, in which the two slotted connecting wires 20 20 are connected with the same type bar 23 through the rock shaft 21 and the connecting wire 18, and one wire 20, is connected with a single spacing key and the other 20, with a double spacing key and there is a third wire 22, connected at one end to the type bar 23, through the'rock shaft'21, and the wire 18, and connected at its other end with the spacing mechanism through the key- .less lever 24.

The paper carriage 4, is mounted at its to the'rail by grooves in the carriage and corresponding grooves in the guide rail, and bearing balls in the rooves. The carriage ,isfree to travel on t e rail on the bearing "balls, I from one end of the rail to the other,

for letter spacing. At its front edge the carriage is provided with the roller 25 which rests an travels with the carriage on the frontrafil 26 (see Figs. 1 and5). It can he spring 30 and the ever 31.

lifted off from the front rail, and the carriage raised for'inspection-of the writing, etc., by taking hold of the front of the carriage and lifting it., Fig. 1 shows the carriage in its normal position, and Fig. 2 shows it in its raised osition. The arr'ows in Figs. 1 and 2 show t e line of vision. When the carriage is raised the guide rail is revolved with the carriage, the two being held together and revolved together on their axes by the bearing balls'27. A sectional view of the bearing balls and their grooves is shown in Fig. 7. There are two bearing balls on the top of the guide rail, and one at the .bottom of the rail intermediately between the two on the top of the rail. The front carriage rail is also pivotedconcentrically with the guide rail 3 and the carriage 4. The front rail is supported by the arms 6 of the shifting frame. he carriage is shifted from its normal position in lower case. to its shifted position in upper case by depressing the shifting frame 6 and the front rail 26. Thecarriage is also shifted to a third position for rinting special characters, whichare carried on certain of the type bars, by lifting the front rail. if A detail of the mechanism for shifting the front rail and the carriage down to upper case and for lifting them to special case is shown in Fig. 5. The shift key 28 is connected with the shift frame 6 by means of the link 29. The carriage isheld in its normal position against ravity by means of the The pin 32 prevents the spring 30 and the lever 31 from raising the shift frame higher-than its normal osition. When it is desired to lift the shiftlng frame .and the carriage to their upper position the spring 33 and the lever 34 assist in overcoming the weight of the carriage. Hence the carriage can be easily There is only one shift key for all three cases. By depressing .the shift key the carriage is lowered to upper case, and by lifting the shift key the carriage is raised to special case, as

shown in dotted lines in Fig. 5. In machines heretofore invented with three types on a bar two shift keys have been provided, one for shifting. to capital letters and one for shifting to figures and other characters, I accomplish the same results by the use of one key by depressing the keyfor one case and lifting it for the other case.

The shift key 28, is connected with the shifting frame 6 by the connecting link 29 (see Fig. 5). At the lower end of the link 29 there is a slot, and on the shift key lever there is a pin 44'which works inthe slot. This arrangement enables the roller43'to disengage the'lever 37 from its obstructive engagement with the prong 38, before the shiftmglpf the carriage 1s begun.

order to insure good alinement it is essential that the carriage be secured against any loose movement on the guide rail. This is effected by the grooves in the rail and the bearing balls 27'in the grooves. Thetwo bearing balls on the top of the guide rail 3, rest in the groove in the top of the rail. Corresponding grooves are provided in the carriage frame 4, which rests on to of the two bearing balls. On the under si e of the guide rail there is one bearing ball which rests in the groove in the bottom of the rail. Below the ball in the bottom groove is a grooved casing. 45, which holds the ball'in the roove in the bottom of the rail and revents it from escaping out of the groove. he carriage frame 4, and the lower casing 45, and the bearing balls 27, and the guide rail 3, are all fastened together by the rack supporting clamps 46 46, which encircle the carriage frame and the casing 45. The rack clamps 46,, can be adjusted by the adjusting screws 47 47, so as to take up any looseness of the carriage on the guide rail.

My resent esca ement comprises the rack 5, an the ;rocker frame 14, with its two reciprocating dogs 65 and 70. The front dog 65 normally engages with the rack. Upon depression of a key the front dog is disengaged from the rack and the rear dog 70,

engaged therewith. Mounted on the base of'the machine is the frame 73, which carries the roller 7 4. The roller 7%. acts as a cam for spacing the dog 70, backward while it is being brought into engagement with the rack. Upon depression of a key'the rack is first disengaged from the dog 65, and under the impulse of the main spring (which is contained in the spring barrel 75, and is connected to the carriage by a connecting band and the hook 76, in the usual manner) the carriage starts forward. The carriage then feeds forward until the rack comes into contact with the dog 70, when it is cammed backward again with the dog by the roller 74, until the key is fully depressed, as is fully described in my said Patent, Number 554,874. The bevel faced wing ,77, on the dog 70, engages with the cam roller to cam the do backward; The dog is rocked forward ar enough to nearly but not quite bring the wing 77 to the rearmost part of the roller 74. If 1t should be brought any farther forward the main spring could not disengage the dog 70, from the rack, but so long as the wing is in en agement with the roller behind the pivotal hne of the roller the pull of the main sprin tends to disengage the dog 70, from the rack and to rengage the dog 65, therewith.

Such of the type bars as have two type keys connected with them (Fi s. 6 and 7) one for single spacing and the 0 er for double spacing, have slotted connecting wires, and t erefore the force of the main spring could not be brought to bear to return them to normal position unless some other means were rovided for that purpose. For such type are I have provided other connecting wires 22 which are connected with 'keyless.

24, connected with a type bar is operated for printing. The keylessv levers 24, are

'connected' with the spacing mechanism and must be lifted when the rocker frame is returned to normal osition, and hence the type bars connects with the keyless levers are started back to normal position by the main spring through the keyless levers and the connecting wires 22.

The-key-levers are fulcrumed in the baseframe to the rear of the type-bar pivots, and

extend under the carriage to'the rear of the Y gage do machine, where the universal bar rests over 1 them.

2 The operation of the machine is as follows: When a key is depressed its key-lever is rocked on the fulcrum bar and the rear end lifted, thus rockin the universal bar up and the connected roe er-frame forwardly so as to disengage dog 65 from the rack and en- 70 therewith and to simultaneously vi rate the ribbon guide 15 to the against the surface to be written on.

platen so as to throw the printing ribbon By the same movement of the key the connected type-bar is simultaneously thrown against the platen and the printing thus effected.

If a lower case letter is to be printed no additional operation is required as the platen is'normally held in its intermediate printing position and the central type character on the type-bar then alines therewith. But if a capital letter is to be printed the capital letter shift key must first be depressed so as to lower the platen .to its lowest pirnting osition where it is in alinement with the owest type-character on the bar; while if one of the s ecial case characters is to be 2 Since the p by s throughout the extent of their printing faces, or in the technical language of the printed the s lift-key must be lifted up so as position where it will aline with the highest to bring the platen to its highest printing.

on the carriage, and in order that the typecharacters shall register with the platen in each of its printing positions (meaning therethat they shall coincide therewith I trade be on their feet), it is necessary to curve the faces of the type relatively to each other so that they will correspond with the curvature of the movement of the platen from the one printing position to another.

This oscillatory movement of the platen to its three printing positions at different levels is clearly illustrated in Fig. 5 and'in Figs. 8, 9 and 10. The corresponding inclination of &

case letter, is at the printing-point 8 and registering thereat or on its feet at the laten, the platen being in its normal central printing position. In Fig. 9 the carriage 4 has been shifted in an oscillatory manner about its guide-rail 3 as an axis, swinging the frontrail 26, the carriage-roller 25 and platen 7, downwardly to its lower, or capital letter, printing position, where the capital letter B 1s shown at the same printing-point 8 and registering thereat or on its feet at the platen. Fig. 10 shows the platen elevated, by an oscillatory movement of the carriage 4, frontrail 26 and carriage-roller 25, to its upper or special case printing position, with a figure or other special case 0 aracter c at the same printing point 8 and also registering thereat, or on its feet at the platen. The printingface of each character a, b, c, is of course curved, as usual, to conform to the curvature of the periphery of the platen itself; but the printing-faces are also curved or inclined relatively to each other, as shown, so as to correspond with the curvature of the oscillatory movement of the platen from one printing position to anothenand this latter curvature or inclination I believe to be novel, and so claim it. Such relative curvature of the printing-faces is of advantage in enabling me to-simplify the platen shifting mechanism.

This application is a continuation and division of my previous application Serial Number 603,845, filed August 25th, 1896,

and is filed in ursuance of a requirement of division of the atent Office.

I do not in this application make any claim or claims to the construction of the ty e bars with a plurality of t es thereon, raving their printing faces inc ined inwardly toward each other so as to register with a pivotally mounted platen in each of its printing 0S1- tions as such construction of the type ars is claimed in my other application serially numbered 469333, filed Dec. 26, 1908.
